This paper explores how the interaction between firm heterogeneity, urban costs and transport costs determines spatial configuration across regions within a simple general-equilibrium model. We spot light on how firm heterogeneity affects the centrifugal and centripetal forces and reshapes the...

The object of this paper is to study the evolution of trade costs and of the agglomeration of production, as well as their relation. The Home Market Effect prescribes increasing agglomeration when trade costs decrease because it is supposed to strengthen. We study the joint variation of trade...

The present paper focuses on spatial sorting as a mechanism behind the well-established fact that there is a central region productivity premium. Using a model of heterogeneous firms that can move between regions, Baldwin and Okubo (2006) show how more productive firms sort themselves to the...

The monocentric city model is generalized to a fully structural form with leisure in utility, congested commuting, and the equalizing of utility and perimeter land price across metros. Exogenous and agglomerative differences in total factor productivity (TFP) drive differences in metro...

This paper analyzes the effects of geographical proximity and agglomeration of FDIs (foreign direct investments) on domestic firms in the privatized glass sector in the Czech Republic. The motivation for this research is based on the scant evidence in Central and Eastern Europe of the effects of...

The purpose of this paper is to analyse the effect of various proximity dimensions on the innovative capacity of 276 regions in Europe within a knowledge production function model, where R&D and human capital are included as the main internal inputs. We combine the standard geographical...

We evaluate the evolution of productivity gains from Chinese cities over time, from 2002 to 2013. In 2002, rural migrants were exerting a strong positive externality on natives' earnings, which were also higher when access to foreign markets through access to sea was higher. In 2007 and then...

This paper uses highly disaggregate data to study the impact of a new metro on firm productivity. The planned-route IV methodology ensures the causality of results and a fine spatial scale detects the geographical scale of the impact. We find that within 750 meters to stations aggregate value...

We study decentralized and optimal urbanization in a simple multi-sector model of a rural-urban economy focusing on productivity differences and internal trade frictions. We show that even in the absence of the typical externalities studied in the literature, such as agglomeration, congestion or...
